Modelling and simulation of complex 3D woven components

3D纺织品预成型件越来越多地用于航空航天工业，以提供增强的性能并缩短复合材料部件的制造时间。通过精心设计，可以制造网状预成型件，其允许将诸如风扇叶片的部件构造成一体。这些网状部件通常具有复杂的几何形状，在3D编织部件中，将需要使用变化的编织图案或逐渐缩放以适应的一种图案。这些模式不一定以直接的方式进行缩放，并且压缩期间的行为将随着设计的缩放而改变。无法将这些尺寸变化的影响纳入设计过程是一个主要的限制，这已经被制造商，如劳斯莱斯。该项目将开发新的方法来模拟这些复杂的组件，将功能性构建到内部几何纺织建模软件TexGen（http：//www.example.com）中。texgen.sourceforge.net

3D textile preforms are being used increasingly in the aerospace industry to provide enhanced properties and improve manufacturing time for composite components. With careful design, net-shaped preforms can be made which allow components such as fan blades to be constructed in one piece. These net-shaped components often have complex geometries which, in a 3D woven part, will necessitate the use of either varying weave patterns or one pattern which is gradually scaled to suit. These patterns do not necessarily scale in a straightforward manner and behaviour during compaction will change as the design is scaled. The inability to incorporate the effects of these changes in dimension into the design process is a major limitation which has been identified by manufacturers such as Rolls-Royce. This project will develop novel methods for modelling these complex components building functionality into the in-house geometric textile modelling software, TexGen (http://texgen.sourceforge.net).
